Abstract
Chlorhexidine release from ethylcellulose films east from solvents of different dichloromethane/ethanol compositions was studied. Release ra te was proportional to the square root of time. Increased ethanol cont ent within the casting solvent significantly enhanced release rate. Re lease rate and cumulative mass released at different time periods (5, 10, 15 and 25 days) were proportional to the solubility parameter of t he casting solvent.
